Description of Forest |
| 7500-4000BC |
Enviromental conditions were relatively stable. Tilia and Acer were present in the Buzuluk area, only around 4000BC. |
| 4000-3000BC late Eneolithic, earliest EBA |
The Buzuluk forest increased in size. The decline in the frequency of Artemisia and Chenopodiacease indicated a moister climate. |
| 3000-2500BC late EBA/early MBA |
THe lake at Buzuluk became a eutrophic Hyprum-Carex swamp. Birch expanded over the swamps's surface. |
| 2500-1500BC late MBA and early LBA |
The forest are in the Buzuluk was slightly reduced and the area of steppe increased. This may be related to an arid climate phase. |
| 1500-400BC |
The forest area of the Buzuluk region increased, but the vegetation cover of the swamp remained stable. |
